[PATCH] D107878: [SampleFDO] Flow Sensitive Sample FDO (FSAFDO) profile loader

[Rong Xu via Phabricator via llvm-commits]

xur updated this revision to Diff 367321.
xur edited the summary of this revision.
xur added a comment.

Discussed with Wei offline: it's better to set fs profile loader as off by default so people can opt-in (rather opt-out).
Once we are done with more perf testing, we will switch the default to on.
